Monel 400 Flanges are primarily composed of nickel and copper, with small additions of iron and manganese that enhance strength and corrosion resistance. This alloy provides excellent resistance to seawater, acidic media, and alkaline environments. It features high tensile strength, impressive toughness, and stable mechanical behavior across a wide temperature range. Monel 400 also resists stress corrosion cracking and maintains its structure under high pressure and thermal variations. These properties make the alloy ideal for flanges used in highly corrosive and demanding applications.
